Hello as mentioned in the data sheet the wp7607 flash size is 256MB however, the root FS size as defined by Yocto is ~40MB, how can I expend the FS size? how much space is actually available on the wp7607? additionally, I noticed that modifying the partitions is not supported by the wp7607 (a post from 12.17) is there any update on that issue? ---

I don’t see there is way to resize the partitions now… But in case you want to include more file in FS, you can try modifying ./meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf ? (parameter UBI\_ROOTFS\_SIZE) ---

I did that and I succeed in creating a larger FS but, without the option to modify partition sizes, when I flash that image the device stops functioning properly (legato components do not function well) this is well understood since I “overrun” existing functionality please advice how it’s possible to use a larger FS thank you ---

The UBIFS size is something a bit from the past, as we are currently not using the generated ubifs rootfs (which has a static size) and use a squashfs rootfs instead (dynamic size, compressed and read-only). The flash layout is fixed on wp76, so it is not possible to resize the rootfs partition once the max is reached. The system can be extended through Legato applications, and/or by putting content in bigger partitions such as /mnt/flash. Overall we recommend the rootfs to remain small for security reason. ---

I understand. but in my case, for example I would like to include ffmpeg to the Yocto build, now image created is bigger then UBI\_ROOTFS\_SIZE so image is not getting built. however if I resize parameter UBI\_ROOTFS\_SIZE, image can be built. how else can I accomplish including more packages to the Yocto build ? ---

not sure if you can remove some packages so that you can run your yocto. e.g. ./meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc ---
**Author:** ![CoRfr](https://sea1.discourse-cdn.com/flex019/user_avatar/forum.legato.io/corfr/32/69_2.png) [@CoRfr](https://forum.legato.io/u/CoRfr)\ **Post date:** [January 29, 2019, 5:38pm UTC](https://forum.legato.io/t/flash-size-wp7607/3805/7 "2019-01-29T17:38:54Z")
And since you’re unlikely to use the ubifs image, you can disable it’s generation by commenting out the 2 lines in `meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf`: ```auto # Add ubifs file system IMAGE_FSTYPES += "2k.ubifs" IMAGE_FSTYPES += "4k.ubifs" ``` So after it should look like: ```auto # Add ubifs file system #IMAGE_FSTYPES += "2k.ubifs" #IMAGE_FSTYPES += "4k.ubifs" ``` You might also need to edit `meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc` to change ```auto for rootfs_type in ubifs squashfs; do ``` by ```auto for rootfs_type in ubifs; do ``` ---

while it does solves the error in build issue, when I flash 'yocto\_wp76xx.4k.cwe" the wp76xx still starting to experience “strage” behaviour, that is because of course the on-board partitioning does not support the image size please advice ---

I can not be limited with the rootFS size to 38MB only I want to make sure, after performing the steps you described: modify: meta-swi/meta-swi-mdm9x28/conf/machine/swi-mdm9x28.conf modify: meta-swi/meta-swi-mdm9x28/recipes-core/images/mdm9x28-image.inc do I still download the image: yocto\_wp76xx.4k.cwe ? ---

if I would like to go in the path of removing existing Yocto packages (still a risk, since it means I always need to fear to reach the maximum limit) can you recommend of large packages I can remove (for example I do not need python support) since ffmpeg is quite large thank you ---

Of course you should download yocto\_wp76xx.4k.cwe ---

Thank you @jyijyi for sharing this document. But I am trying to get image (xxx.cwe) file ready for production and it requires all modules with my application included during the build time. I have a build setup and able to build image successfully using make image\_bin. I would really appreciate if you could help me with resolving this issue. Cheers, ---

> [@jyijyi](#): > > ere o @jyijyi Thanks for responding. So there is no way for me to add large packages with the yocto build. eg. ffmpeg, qt5 in this module? [Next page](https://forum.legato.io/t/flash-size-wp7607/3805.md?page=2)
